Produktinformation "PCIe-LM4 PCI Express Board, 4-ch Load Cell Input and 2-axis Motion Control"
The PCIe-LM4 CR is a multifunction PCI Express x1 board for PC-based measurement and control. It brings together four strain gauge (load cell) inputs, four differential analog inputs, a 2-axis pulse output and encoder interface, two 16-bit analog outputs and sixteen isolated digital inputs and sixteen digital outputs on a single card.
Each load cell and analog input uses a 24-bit ADC with a sampling rate of up to 15 kS/s. The motion section supports CW/CCW, Pulse/DIR and EA/EB modes, which suits engineers who need pulse-based axis control and encoder feedback alongside sensor measurement in one host PC.
A 4-bit Card ID switch lets you tell boards apart in software when two or more PCIe-LM4 cards are fitted to the same computer. Software support includes DLL access and sample programs for several development environments.
Applications
- Load cell and strain gauge measurement
- Two-axis pulse-based motion control with encoder feedback
- Multi-channel analog and digital I/O in PC-based systems
